Element for Dry Joining that Provides Insulation, and Method Incorporating said Element

ABSTRACT

The present invention relates to a laminar element in the form of a plate, which is adhered to the back of a tile, for dry joining and which provides insulation; said element is used for placement between a floor or deck and a covering material. The design of the element in a squared shape with pressure-sensitive adhesive “male sections” makes it possible to dry-install surfaces, both in new jobs and renovation. The aim is to obtain a finished product with more advantages for the final installation thereof in construction works, and which provides insulation of several types, including acoustic, thermal and insulation against moisture. The invention is applicable for all types of materials used as elements in finishing in the construction sector, both natural and artificial materials, and in rigid tiles or in mosaics.

The present invention relates to an element for dry joining that provides insulation, and a method for dry joining incorporating said element, wherein said element is used for placement between a covering formed by natural or artificial cladding materials, such as tiles, natural stone, wood or mosaics on a floor or deck.

FIELD OF THE ART

This invention relates to the field of processes and elements that can be used in construction and building.

STATE OF THE PRIOR ART

The structures of floors or decks of buildings generally tend to be coated by means of coverings, which can be of several types, such as natural or artificial claddings such as tiles, natural stone, wood, mosaics, parquet flooring, etc.

These coverings are usually wet-fixed to the floors or decks by means of cement mortars, adhesive mortars, vinyl adhesives, reagents and the like, etc.

Insulation elements (acoustic, thermal, and any other type) are also known that are formed by sheets of foamed materials and/or sheets of rubber material or similar type that are placed between the structure and the compression or levelling layer, before receiving the covering material.

However, installation of such insulation typically occurs independently to placement of the coverings. In addition, both operations are still excessively slow and laborious.

BRIEF DESCRIPTION OF THE INVENTION

The present invention aims to overcome the drawbacks associated with the placement of the coverings of the type indicated at the beginning and associated with the installation of insulation, characterised by consisting of and using a square or rectangular low/medium density laminar material (1) installed at the bottom of a tile and designed with insertions in a squared shape, namely, both sides with symmetrical female grooves (2) and two sides with symmetrical male sections (3), coinciding in the design between grooves and male sections, in the form of an insertion type puzzle. The male sections will have a built-in self-adhesive on its upper side, protected (4) with a plastic or paper-silicone film.

This element for dry joining which provides insulation, previously installed on the lower back of a tile of any type, can be applied directly over the structure, compression or levelling layer, raised structure for raised flooring or old surfaces of all types, ceramic, marble, granite, terrazzo, wood, parquet flooring, etc. all without the need to use any wet fixing (mortars or the like) or without having to add an additional adhesive.

Fixing tiles to each other is done in two ways, first by the actual design of the laminar element (1) in a squared shape incorporated onto the lower back of the tile, inserting the male/female section (puzzle type), and the second by using the self-adhesive incorporated into the upper side of the male section (4), fixing the element of a tile with the underside of the continuous tile, creating a successive joining, between each other, of all tiles installed on the covering.

The advantages of the present invention are disclosed in this descriptive memory, although hereinbelow we mention the most essential by way of non-limiting example, namely:

-   -   Easy and quick installation, with the ensuing reduction in         labour costs for the installation of finishing elements during         construction works.     -   No professional workmanship required.     -   Improves the technical properties of the coverings, since the         joining element provides not only sound insulation, but also         other forms, such as insulation against moisture, avoiding the         possible absorption of water by capillary action, for example in         marble or wood, reducing the risks of staining or warping.     -   Provides aesthetic design to the covering due to the designed         symmetry, and there can be various combinations and types of         interconnections.

DESCRIPTION OF THE INVENTION

The element for dry joining which provides insulation (1) consists of a sheet (1) in the form of a plate installed on the back of a tile, designed in a squared shape, with symmetrical male (2)/female (3) insertions which includes at least the following characteristics:

a) Laminar element (1) from 1 to 20 millimetres thick.

b) Density of the element from 30 to 400 kg/m³.

c) Design with insertions in a squared shape on the four sides, symmetrical male (3) and female (2) sections.

d) The male sections (3) will have a self-adhesive on the upper side weighing 50 to 200 grams/m², protected with plastic (4) or silicone-paper film, which is removed when installed. 

1. Element and method for dry joining that provides suitable insulation, in particular, to be arranged between a covering and a floor or deck, comprising a laminar element having a thickness of 1 to 20 millimetres.
 2. Element according to the claim 1 wherein said element is adhered to the back of a tile that can be arranged coincident or non-coincident with respect to the shape thereof. 3-4. (canceled)
 5. Element according to claim 1 wherein the self-adhesive weights from 50 to 250 grams/m2, protected with plastic or silicone-paper film, which is removed when the tile is installed.
